Abstract
The recently developed herbicide saflufenacil was evaluated in six field trials between 2008 and 2011 for weed control in maize (Zea mays) crops Trial sites varied considerably in soil characteristics and weed spectrum No phytotoxicity or visual damage symptoms were observed in any of the six cultivars planted When used alone at 70 or 105 g ai/ha saflufenacil provided effective control of annual broadleaf weeds including atrazine and dicambaresistant fathen (Chenopodium album) but had little activity on grass weeds In combination with acetochlor both rates of saflufenacil provided good control of annual grass and broadleaf weeds in all but one trial In crops with a high weed pressure especially grass weeds a follow up postemergence herbicide would be required to maximise control Combinations of saflufenacil with up to 1200 g ai/ha of dimethenamidp were generally less effective than with acetochlor A strong negative relationship was evident between weed density and maize silage or grain yields
